Referring to all the figures of the drawings, in all of-which like partsare designated .by like reference characters, at 10, I show a tankadapted to becarried on a wheeled scrubbing truck. Inturned flanges 12are formed on the upper edgeof the tank, and a transverse channel ironbrace 13 is disposed between the sides of thetank to provide areenforcement therefor. Saidflanges and said channel iron brace areadapted to secure my improved mop wringer, generally indicated by thereference numeral 14, on the upper edge kof the tank in a manner whichwill hereinafterbe described in detail. kFor purposesfof illustrationand that a better understanding of -my invention may -be had 'I haveshown the same applied -to a Wheeled scrubbing tank; however, vit is to2Q same between shoulders 32 on the ro-ds and be understood that I donot wish to limit myself tothe specific employment of my improvedwringer herein illustrated and described, inasmuch as the same may beemployed in numerous different ways from the manner herein embodied.

The wringer 14 preferably comprises a frame having a pair of frame endplates 21 and 22 formed of pressed sheet steel, an notermediatelydisposed pressed sheet steel frame plate 23, `disposed more adjacent theend plate 21, and a pair of spacer rods 24l and 25 provided withthreaded reduced ends 26 and 27 adapted to project through alignedapertures 28 and 29 inthe frame plates 21, 22, and 23. Rod reduced ends26 and 27 are relatively long and are adapted to receive spacer bushings30 and 31. Said spacer bushings abut against the frame plate 23,`clamping the Y the bushings, lwhen clamping nuts 33 are screwed ontothe rods to clamp the frame end plate`21v thereon. Frame clamping nuts34 lretain the frame end plate 22 butted against shoulders 35 on theopposite ends of the rods.

A pair of angular frame clips 36l and 37 are preferably riveted to theAframe end plate 22 in spaced relation to each other and are adapted tobe projected beneaththe flangesy 12 of the tank 10. An angular wringerclamp 38 is secured to the other frame end plate 21 intermediate itsends. Said clamp is formed with a laterally disposed portion 39 having aslot 40 therein. Althreaded Clamping stud is carried by the channel ironbrace 13 intermediate the ends thereof and is adapted to project intothe slot 40 when the wringer is placed on the edge ofthe tank with theclips under the flanges l2. A clamping nut 42 having a threaded aXialrecess in one-of its ends is threaded ontothe stud to detachably securethe wringer on the tank 10. The nut 42 is provided with a radial boreintov which a handle 41V is carried and projects laterally thereof andmay be grasped by the hand of an operator to either clamp or releaseclamp of the wringer on the suport.- f Y v pThe driving mechanism andspring tensioning and shifting mechanism for the Wringer rolls 45 and46, the former being shiftable, and the latter being fixed, comprises apair of mechanisms disposed, one on each side of the frame, and aresimilar in construction and operation one being right hand andthe otherleft hand, except that a handle 3 and crank4 are included in themechanism on one side of the frame generally indicated by the. referencenumeral Y5,k

while a lever 6 in the mechanism, generally indicated at 8, takes theplace of the handle and'c'rank3 and 4. In view of the similarity l ofconstruction and operation of the driv- 65V ing, shifting and tensioningmechanisms 5 slid longitudinally therein relative to the end plates`22and 23. The slots 47 and 48 are provided with recesses in the endthereof more adjacent the roll 46, said recesses being large enough topermit the shaft 52 to be inserted therein so that the grooves 51 alignwith the slots 47 and 48 and allow the shaft to slide longitudinallytherein, and provide abearing support for the shaft. Idler shaft 49 isprovided with portions projecting laterally of the slots and areprovided with bores 53 and 54 adjacent the ends thereof.

`Roll 46 is preferably composite and coinprises a rotatable shaft 6lhaving peripheral grooves 62 and 63 disposed adjacent the ends thereof.Said shaft is journaled in bearings 93 and 94 carried in alignedopenings in the plates 22 and 23. A radial recess 64 is pro* vided inthe shaft 'for the reception of a lock pin 65 having a threaded end 66screwed into a threaded aperture in bushings 67 secured to the shaftadjacent each end thereof. A tubular core 68 having end internal grooves69 lis disposed over the bushings 67 with the bushings 'abuttingl theshoulders formed by Y A threaded opening 70 is and is adapted toprovide'a non-slipping drive for the roll 45 when a mop or other articleis passed. between the rolls. The sur.- face is provided with anaperture 76 in alignment with apertures 64 and 70 for the pin 65 bywhich access maybe had to the same to remove the core 68 and surface 75.The ends of the shaftfare provided with reduced threaded ends, one ofwhich receives the handle crank 4 non-rotatably secured thereto by a nut73, while a nut 74 is threaded onto the opposite end of the shaft.

The driving mechanism forthe rolls actuated by rotation of the handlecrank 4, cornprises a cam carrying link 77 pivoted at 7 8 to the handlecrank adjacent its shaft engag ing end, and is bent away from the crankat 79 disposing the free end thereof in alignment with a peripheralgroove 62 in the shaft. Pawl disks 8O and 81, as best shown in Figs. 13and 14, are preferably riveted to the ends of the link 77, all of whichare provided with Vvcentrally disposed slots 82, 82" and 82". The camdisks 8O and 81 have cam surfaces 84 relieved at the high point 86 toform ya hook shaped endi85. Asbest shown ini-'Figi 17, the link 77: andpawl disks-80 y.and *81, 'when riveted together, form acentral ci-rcularrecess, 'the slot82 being larger' than the-l slots 82 an'd82 in therpawldisk80 and link 77, respectively.

Aslotted bushing 87, Fig. 18, carried' by one end of a link 88,'isprovided with aflange 89 and an intermediate groove 90. The J innersurfaces of the pawl disks kand link cooperate with the externalsurfacesof the bushing87, as best shown in Figs. 9 and l19. The vouterassembly ymay yhe rotated around the bushing, thebushing being heldwithin the Yslot of the pawl disks and linkby the liange 89 in thegroove82. 'A pawl 103 is slidably carried in an inclined slot 104 in the link88 and adaptedto be engaged lby the cam and'elevatedin the slot when thehandle crankis rotated in one direction, and adapted to loe engaged bythehook 85y tomove the pin to the. base of the slot when the handlecrank is rotated in the opposite direction to render the rhook 85, .link77 and tension link y88 a rigid lever. n p

The 4link 88 is 'provided with a ylug 91,as best shown in Fig. l2,projecting from one end thereof adapted `to enter a slot 92 formed inthe adjoining end of 'spring tension rods and are rigidly secured toeach other. A washer96 is carried on the rod adjacent the link 88. Rods15y are preferably Adisposed parallel with the frame end plates and the`handle, crank, the .free ends thereof being adapted to project through.the .radial bores cli- 53 andy 54 in .the idler shaft'49. A coiledspring 16 is carried by the rod 15 and is compressed between the idlershaft and ya nut 97y threaded onto the end of the rod.

A stop member'57 adapted to limit rotative movement of the shaft 49 isprovided, preferably comprising a collar around an end of the portion 52of the shaft 49 and engag- Y ing the exterior wall of the frame endplate f 22 adjacent to and bridging the slot 47 therein. A threadedtransverse bore 59 is provided in the collar for the reception of a setscrew 60 adapted to non-rotatably secure the collar on the shaft 49. Aradially extending arm preferably formed integral with the collar isprovided having a laterally projecting portion 56 disposed into the slot47. Said portion is formed with flat inclined sides 160 and 161 whichmay alternately engage the Zopposed faces 162 and 163 of the slot 47 tolimit the rotative movement of the shaft 49 when the same is rotated andthereby prevent accidental disengagement of the links 88 and 77. Thus,when the handle is rotated to move the roller 45 towards the roller 46,the lower flat side 161 of the portion k56 will engage the lower face163 of the slot,-and accordingly provide a stop to limit rotativelmovement of the rshafty 49. Conversely, when the handle is rotated inthe opposite direction to space the rollers 45 and 46, the shaft 49 willrbe rotated into the position in which the upper side wall 160 thereofwill engage Vthe'upper face l162 of the slot and thus limit rotativemovement of the shaft 49 in the lopposite direction.

Operation of the above described wringer, assuming the same to be in theposition illustrated in 2 and 5 of the drawings, wherein the rolls 45and 46 are out of contact with cach other, is as follows:

A mop head is elevated from the tank into al Iposition between the rollsby one hand of the operator. and the operator grasps Vthe handle 3 withhis free hand rotating the han-v dle clockwise. The levers 4 and 6 andlinks 77 will be swung to the right drawing the shiftable roll 45towards the fixed roll 46 and the U-'shaped recesses of the links anddisks 8O and 81-will engage the peripheral grooves 62 and 63. T heshiftab'l-e roll will engage the mop head and compress the same betweenit and the roll 46, the spring tensioning rods 15 permittingthe mop headto be so disposed. Continued rotation of the crank clockwise rotates theroll 46 which in turn rotates the roll 45 and forces the mop head frombetween the rolls n-'ringing the water therefrom. The U- shaped recessesner-mit free rotation of the shafttl and at the same time retain theroll 45 in shifted position against the tension of the springs 16.During` rotation of the handle crank. in a clockwise direction the. cams84 will elevate the pin in the slot 104 and thereby permit free rotationof the handle crank.

l/Vhen it is desired to release the mop. the lever 4 is rotated counterclockwise carrying with it the link 77 until the hook 85 engages the dog103 which causes the link 77, tension link 88 and rod 15 to form a ri,ai d leverwith the shaft 52 as the fnlcrum and the point of connection78 as power, with the slots-82, 81 and 82 and the slot in th-e bushing87 aligned, and lifts the rigid composite 'lever soformed out ofengagement with the groove 62 on the roller shaft 61 and by an eccentricmotion forces the roller 45 away fromj the roller 46. The movement iscontinued until a limit is reached by virtue of the shaft 49- engagingthe ends of the slots 47 and 48,
